Abstract
Oscillometry has been around for almost 70 years, but there are still many unknowns. The test is performed during tidal breathing and is therefore free from patient-dependent factors that could influence the results. The Forced Oscillation Technique (FOT), which requires minimal patient cooperation, is gaining ground, particularly with elderly patients and children. In pulmonology, it is a valuable tool for assessing obstructive conditions (with a distinction between central and peripheral obstruction) and restrictive disorders (intrapulmonary and extrapulmonary). Its sensitivity allows the assessment of bronchodilator and bronchoconstrictor responses. Different lung diseases show different patterns of changes in FOT, especially studied in asthma and chronic obstructive pulmonary disease. Because of these differences, many studies have analysed the usefulness of this technique in different areas of medicine. In this paper, the authors would like to present the basics of oscillometry with the areas of its most recent clinical applications.

Lu YS, Chou CC, Tseng YH, Lin KL, Chen CH, Chen YJ. Cardiopulmonary functional capacity in Taiwanese children with ventricular septal defects. Pediatr Neonatol 2023; 64:554-561. [PMID: 37003956 DOI: 10.1016/j.pedneo.2023.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 12/23/2022] [Accepted: 02/09/2023] [Indexed: 04/03/2023] Open
Abstract
BACKGROUND Children with ventricular septal defects (VSDs) are considered to have no difference in cardiopulmonary functional capacity with healthy children of the same age; however, studies have shown contradictory findings. The aim of this study was to assess whether Taiwanese children with VSDs exhibited cardiopulmonary deficits. METHODS This is a retrospective cohort study with the data collected from January 2010 to December 2021. All patients and controls (age-, sex-, and body mass index -matched) underwent cardiopulmonary exercise testing (CPET) and pulmonary function test. RESULTS In total, 157 VSD patients (80 patients with surgically closed VSDs, 77 patients with unrepaired VSDs) and 157 healthy controls were recruited. Pulmonary function test showed significant among-group differences in maximal voluntary ventilation (MVV) (p = 0.015). The surgically closed group had lower MVV compared to the control group. Regarding CPET, we found VSD patients had lower peak oxygen uptake than the controls (surgically closed group: 30.84 ± 6.27 ml/kg/min; unrepaired group: 32.00 ± 5.95 ml/kg/min; control group: 36.76 ± 6.50 ml/kg/min, p < 0.001). There was also significant among-group differences in aerobic capacity (surgically closed group: 21.20 ± 4.39 ml/kg/min; unrepaired group: 21.68 ± 4.47 ml/kg/min; control group: 26.25 ± 4.33 ml/kg/min, p < 0.001). In addition, the surgically closed group had lower heart rate average at anaerobic threshold than the control group (surgically closed group: 138.11 ± 16.42 bpm; control group: 145.78 ± 15.53 bpm, p = 0.002). CONCLUSION Taiwanese children with VSD, whether surgically closed or not, have poorer cardiopulmonary performance than age-matched healthy children, and the results of the surgically closed group were even worse.

J Am Heart Assoc 2023; 12:e028538. [PMID: 37548158 PMCID: PMC10492940 DOI: 10.1161/jaha.122.028538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 06/08/2023] [Indexed: 08/08/2023]
Abstract
Background Older adults with a congenital ventricular septal defect (VSD) recently exhibited reduced heart rate variability and exercise capacity. It is unknown whether these findings affect health-related quality of life. Methods and Results Adults with VSDs and healthy controls, all concurrently included as part of another clinical study, completed the Danish National Health Survey questionnaire. Questionnaire data distributed to the general population were included and matched 10:1 with patients. Thirty patients with surgically closed VSDs (mean±SD age, 51±8 years), 300 adults from the general population (mean±SD age, 50±8 years), and 30 controls (mean±SD age, 51±9 years), as well as 30 patients with unrepaired VSDs (mean±SD age, 55±11 years), 300 adults from the general population (mean±SD age, 55±12 years), and 30 controls (mean±SD age, 55±10 years) completed the questionnaire. Educational level, social relations, and physical activity were comparable between groups. A larger proportion of patients with unrepaired VSDs compared with the general population experienced migraine (47% versus 24%; P=0.04), whereas more patients with surgically closed VSDs were affected by depression (13% versus 4%; P=0.02). For health-related quality of life, patients with surgically closed VSDs reported lower physical functioning (P<0.01), physical component summary (P<0.01), general health perception (P<0.01), and higher stress score (P=0.03) compared with the general population and healthy controls. Patients with unrepaired VSDs reported lower scores on physical functioning (P=0.03), bodily pain (P<0.01), and mental health (P=0.02), and a higher stress score (P=0.03), than controls. Conclusions Older patients with VSDs report lower self-perceived physical functioning, lower general health, and higher stress levels, all in line with previous findings, like lower exercise capacity and dysfunctional cognitive abilities, in adults with VSDs. Incessant follow-up is paramount, as neither successfully closed nor hemodynamically insignificant VSD is equivalent with untroubled healthy aging.

Practice Patterns in the Management of Pressure Restrictive Perimembranous Ventricular Septal Defects: A Multinational Survey. Pediatr Cardiol 2022; 44:845-854. [PMID: 36538052 DOI: 10.1007/s00246-022-03073-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 12/05/2022] [Indexed: 12/24/2022]
Abstract
Indications for the closure of pressure restrictive perimembranous ventricular septal defects (pmVSD) are not well established in the pediatric population. We sought to assess practice variability among pediatric cardiologists in the United States (US), Canada, Australia, and New Zealand. A survey ascertaining practice patterns, including case vignettes with incremental progression of disease severity, was designed and administered through representative professional cardiac organizations and email listservs in the designated countries. Among the 299 respondents, 209 (70.0%) were from the US, 65 (21.7%) were from Canada and 25 (8.3%) were from Australia and New Zealand. Indications for pressure restrictive pmVSD closure included the presence of left ventricular (LV) dilation for 81.6% (244/299) (defined as z-score ≥ 2 for 59.0% (144/244) and ≥ 3 for 40.2% (98/244)) and significant pulmonary-systemic flow ratio (QP:QS) for 71.2% (213/299) [defined as ≥ 1.5:1 for 36.2% (77/213) and ≥ 2 for 62% (132/213)]. US pediatric cardiologists elected to close restrictive pmVSD at lower LV z-score and QP:QS ratio cut-offs (p-value 0.0002 and 0.013, respectively). In a case vignette, 63.6% (173/272) chose to intervene if there was right coronary cusp prolapse with stable mild aortic regurgitation. Of the remaining cardiologists, 93% (92/99) intervened if the aortic regurgitation was progressive (from trivial to mild). Commonly identified indications with variable thresholds for closure of pressure restrictive pmVSDs included the presence or progression of LV dilation, significant volume loading, and aortic valve prolapse with regurgitation. US pediatric cardiologists may have a lower threshold for pmVSD closure.

Abstract
Decision-making in congenital cardiac care, although sometimes appearing simple, may prove challenging due to lack of data, uncertainty about outcomes, underlying heuristics, and potential biases in how we reach decisions. We report on the decision-making complexities and uncertainty in management of five commonly encountered congenital cardiac problems: indications for and timing of treatment of subaortic stenosis, closure or observation of small ventricular septal defects, management of new-onset aortic regurgitation in ventricular septal defect, management of anomalous aortic origin of a coronary artery in an asymptomatic patient, and indications for operating on a single anomalously draining pulmonary vein. The strategy underpinning each lesion and the indications for and against intervention are outlined. Areas of uncertainty are clearly delineated. Even in the presence of "simple" congenital cardiac lesions, uncertainty exists in decision-making. Awareness and acceptance of uncertainty is first required to facilitate efforts at mitigation. Strategies to circumvent uncertainty in these scenarios include greater availability of evidence-based medicine, larger datasets, standardised clinical assessment and management protocols, and potentially the incorporation of artificial intelligence into the decision-making process.

Abstract
Background Congenital ventricular septal defects (VSDs) are considered to have benign long‐term outcome when treated correctly in childhood. However, abnormal parameters are described in younger adults, including impaired heart rate variability (HRV). It is not known whether such abnormalities will deteriorate with age. Therefore, HRV and cardiac events, such as premature ventricular contraction, were evaluated in patients aged >40 years with congenital VSDs and compared with healthy peers. Methods and Results A total of 30 surgically closed VSDs (51±8 years, repair at median age 6.3 years with total range 1.4–54 years) with 30 healthy controls (52±9 years) and 30 small, unrepaired VSDs (55±12 years) with 30 controls (55±10 years) were all equipped with a Holter monitor for 24 hours. Compared with healthy peers, surgically closed patients had lower SD of the normal‐to‐normal (NN) interbeat interval (129±37 versus 168±38 ms; P<0.01), SD of the average NN intervals for each 5‐minute segment of a 24‐hour HRV recording (116±35 versus 149±35 ms; P<0.01) and 24‐hour triangular index (31±9 versus 44±11; P<0.01). SD of the NN intervals, SD of the average NN intervals for each 5‐minute segment of a 24‐hour HRV recording, and triangular index were comparable between unrepaired VSDs and healthy peers. SD of the NN intervals was <100 ms in 22% of surgically closed and 10% of unrepaired VSDs, whereas controls were within normal ranges. A high number of premature ventricular contractions (>200 events) was registered in 57% of surgical patients compared with 3% of controls (P<0.01), and 53% of unrepaired VSDs compared with 10% in controls (P<0.01). Conclusions Adults aged >40 with congenital VSDs demonstrate impaired HRV, mainly among surgically closed VSDs. More than half demonstrated a high number of premature ventricular contractions. These novel findings could indicate long‐term cardiovascular disturbances. This necessitates continuous follow‐up of VSDs throughout adulthood.

Abstract
Background Ventricular septal defects (VSD), when treated correctly in childhood, are considered to have great prognoses, and the majority of patients are discharged from follow‐up when entering their teens. Young adults were previously found to have poorer functional capacity than healthy peers, but the question remains whether functional capacity degenerates further with age. Methods and Results A group of 30 patients with surgically closed VSDs (51±8 years) with 30 matched, healthy control participants (52±9 years) and a group of 30 patients with small unrepaired VSDs (55±12 years) and 30 matched control participants (55±10 years) underwent cardiopulmonary exercise testing using an incremental workload protocol and noninvasive gas measurement. Peak oxygen uptake was lower in participants with closed VSDs than matched controls (24±7 versus 34±9 mL/min per kg, P<0.01) and with unrepaired VSDs than matched controls (26±5 versus 32±8 mL/min per kg, P<0.01). Patients demonstrated lower oxygen uptake from exercise levels at 20% of maximal workload compared with respective control groups (P<0.01). Peak ventilation was lower in patients with surgically closed VSDs than control participants (1.0±0.3 versus 1.4±0.4 L/min per kg, P<0.01) but similar in patients with unrepaired VSDs and control participants (P=0.14). Exercise capacity was 29% lower in older patients with surgically closed VSDs than healthy peers, whereas younger patients with surgically closed VSDs previously demonstrated 18% lower capacity compared with peers. Older patients with unrepaired VSDs reached 21% lower exercise capacity, whereas younger patients with unrepaired VSDs previously demonstrated 17% lower oxygen uptake than healthy peers. Conclusions Patients with VSDs demonstrate poorer exercise capacity than healthy peers. The difference between patients and control participants increased with advancing age—and increased most in patients with operated VSDs—compared with previous findings in younger patients. Results warrant continuous follow‐up for these simple defects.

Abstract
Ventricular septal defects (VSDs) have recently demonstrated poorer functional outcome with disrupted ventricular contractility during exercise in young patients. It is not known whether this will change with age. Therefore, echocardiography was performed in older patients with congenital VSDs, either surgically closed or unrepaired and all without Eisenmenger physiology, to compare functional outcomes with healthy peers. Transthoracic echocardiography was performed at rest and during supine bicycle exercise, with tissue velocity Doppler for assessment of primary end points: isovolumetric acceleration and systolic velocities. In total, 30 surgically closed VSDs (51 ± 8 years) with 30 healthy controls (52 ± 9 years) and 30 unrepaired VSDs (55 ± 12 years) with 30 matched controls (55 ± 10 years) were included. Surgical patients displayed lower right ventricular (RV) systolic and early diastolic-filling velocities compared with controls, p <0.01, lower tricuspid annular plane systolic excursion (17.8 ± 5 vs 22.7 ± 3mm, p <0.01) and lower fractional area change (37.8 ± 6 vs 46.4% ± 7%, p <0.01). Unrepaired VSDs also had lower RV fractional area change than matched controls (39.9 ± 7 vs 48.4% ± 7%, p <0.01). Both patient groups had more tricuspid regurgitation and larger RV outflow tract dimensions than controls, p <0.01. During exercise, isovolumetric acceleration and systolic velocities were lower in both patient groups compared with controls, with the difference increasing with workload level. In conclusion, adults in their mid-50s with surgically closed or unrepaired VSDs have abnormal RV function at rest, with even more pronounced differences during exercise. These results suggest that a VSD, whether repaired early or considered hemodynamically insignificant, is not a benign lesion and continuous follow-up of adults is warranted.
